Text (UL): Counter target spell that targets a creature.
Can only target a spell that is currently targeting a creature. [D'Angelo 1999/02/15]
The spell targets the creature if it uses the word "target" in its text. If the word "target" isn't there, then the spell is not targeted. [Urza's Legacy FAQ 1999/02/03] One exception, Auras target even if they don't use the word target. [D'Angelo 1999/02/18]
If a spell is modal (see Rule G13.13), use the target(s) of the current mode only for this check. [D'Angelo 1999/02/15] Targets for the other modes are never selected.
It means "targeting at least one creature" not "exactly one creature". [D'Angelo 1999/03/12]
If the spell's target leaves play before this spell resolves, Intervene will be countered since it no longer targets a spell that targets a creature. [Jordan 2001/02/12]
Note - This card was of type Interrupt. It is now an Instant. [Oracle 1999/05/01]
